After investigating with the Departments of Planning and DPW, their inventory and pipeline reports, U.S. census data, MLS data, Andy Sirkin, NAHB and a half dozen other resources, we came up with the following estimates about San Francisco housing inventory:
- 124,000 housing units are owner occupied. About 4% to 4.5% of San Francisco houses and 6.5% to 7% of condo, co-ops and TIC units are sold annually.
- 222,000 housing units are rented out and 25,000+units are vacant at any given time
* These are very approximate estimates based on data from the U.S. Census, the SF Depts. of Planning & Public Works, MLS and other sources deemed reliable.
